The creator of pgdog is also the creator of pgcat, so I think they probably don't need to do this.
pg cat
pg dog
What's he going to name the next version?
pg emu ?
In fact postgresML took naming heat because Postgres is right there in the name and they weren't affiliated with the brand. "pg" is just two letters. like WP-engine (literally the name as they say it is "double U P engine").
And a cat and a dog is fun.
don't think they're trying to get one over on you.
